These 15 urban design projects are reinventing cities for a zero-carbon future

May 29, 2019

As the world moves to a zero-carbon future, cities will be key places to transform–particularly buildings, which account for more than half of emissions in most cities. Reinventing Cities, a competition launched two years ago by C40 Cities, a network of mayors focused on finding solutions to climate change, asked architects to reimagine new uses for vacant and abandoned spaces in six cities: Chicago, Madrid, Milan, Paris, Oslo, and Reykjavík. These are the winning proposals; the winning teams now have the chance to buy or lease each site to develop the projects.
